Observations of seawater carbonate chemistry in the Southern California Current
The ocean has taken up roughly a quarter of the total anthropogenic carbon emissions (Gruber et al., 2019). This addition causes changes in carbonate system equilibrium, decreasing ocean pH, which impacts marine organisms, ecosystems, and humans reliant on marine resources (Doney et al., 2020). The...

The ocean has taken up roughly a quarter of the total anthropogenic carbon emissions (Gruber et al., 2019).

The study of the changing carbonate chemistry and its impact on the ocean requires the refinement of measurement techniques, observational programs, models and the sharing of data. Chapter 1 focuses on measurement techniques by assessing the stability of tris pH buffer in artificial seawater stored in bags.
